2 Claims.

sealed by means of a perishable disc which may be readily replaced whenthe lubricant in the container has been removed andthe container hasbeen refilled for further use.

Still another object of the invention is to provide a closure ring usedin securing the seal-. ing disc in position, which may be rotated in aclockwise direction to secure the sealing disc, but prevented fromreverse movement to remove the contents of the container withoutdestroying the sealing disc.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing:

Fig. 1 is a disassembled view illustrating an oil container with a cap,constructed in accordance with the invention.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1 when the elementsl2, 8 and 6 are in assembled condition.

Referring to the drawing in detail, the container comprises a bodyportion indicated generally by the reference character 5 and in thepresent showing is in the form of a can with a neck 6 rising therefrom.

The neck 6 is formed with an inwardly ex tended annular flange l whichprovides a support for the seal disc 8 which is constructed preferablyof perishable material so that when the disc is mutilated the contentsof the container may be poured therefrom.

Secured to the inner surface of the flange l, is the spring arm 9 towhich the pin I0 is secured, the pin ID extending through an openingformed in the flange 1, as clearly shown by Fig. l of the drawing. Theseal disc 8 is also provided with an opening indicated at H, whichopening 2 is adapted to be positioned over the pin l0, so that the pinIll may extend therethrough, securing the seal against rotation on theflange 1.

The neck 6 is formed with threads that cooperate with threads of theclosure ring l2, which is provided with the inwardly extended annularflange I3, to the under side of which is secured the ratchet ring Mwhich has its teeth so disposed that they contact the upper end of thepin l0, permitting rotation of the closure ring I2 in a clockwisedirection, but preventing rotation of the closure ring [2 in ananti-clockwise direction, thereby making it impossible to remove thering l2 until the pin ID has been forced inwardly to disengage the teethof the ratchet ring I4, and since this can only be done after the sealdisc has been mutilated, it will be obvious that removal of the contentsof the container by an unauthorized person will be readily detected.

After the contents of the container have been removed and the containeris refilled for further use, another seal disc 8 is positioned. on theflange I and the closure ring rotated in a clockwise direction to clampthe disc in position, sealing the mouth of the can.

As previously stated, to remove the contents of the can, the disc 8 mustbe mutilated, which mutilation of the disc will afford access to thespring arm 9, which may be forced inwardly to allow the closure ring tobe rotated in an anti-clockwise direction to remove the closure ring andpermit of the application of another seal disc to seal the containerwhen it is refilled for further use.

From the foregoing it is believed that the construction and operation ofapplicants" sealing device for refillable containers will be clear andthat further description of the container is unnecessary.

Having thus described the invention, what is claimed is:

1. In a refillable container, 9. body, a threaded neck forming a part ofthe body, an annular flange extending inwardly from the top edge of theneck, a spring pressed lock pin extending upwardly through said flange,a perishable seal disc positioned on said flange closing the container,said seal disc having an opening through which the locking pin extends,a removable closure ring rotatable in a clockwise direction mounted onthe neck in contact with said disc, ratchet teeth on the closure ringcooperating with said pin normally preventing reverse rotation of saidclosure ring to remove said ring and seal disc, and said 3 pin adaptedto be moved out of engagement with said ratchet teeth, releasing saidring for reverse rotation, upon mutilation of said disc.

2. In a refillable container, a body, a neck forming a part of the body,said neck having external threads, an inwardly extending annular flangeformed on the top edge of the neck, a spring pressed pin supported bysaid flange extending upwardly through an opening in said flange, aperishable sealing disc resting on said flange, said sealing disc havingan opening through which the pin extends, a closure ring threaded on theneck adapted to clamp said seal disc against said flange, and a ratchetring secured to the ring engageable with said pin permitting rotation ofthe closure ring in one direc- REFERENCES CITED The following referencesare of record in the flle of this patent:
